The pointset which the plate c is supne t byt iiia s oc t tl as t to appear in Fig. 2. The wheel it gears with InFig. 1, e portion of the wheel W is broken out to show the mechanismunderneath it.

Between the wheel W and'the bracket H the shaft 01 is threaded, and uponit are the two n illed nuts n n. By screwing down these nuts against thewheel W the letteris pressed against theshoulder of the shaft 01, andsuiticient friction produced between them to insure the revolution ofthe wheel W with the shaft, which, as before mentioned, is at the rateof one revolution in seven days. On the circumference of the wheel W,Fig. 1, are six recesses, b, and six full parts, F, each recess and anadjacent full pert embracing oneseventh of the entire circumference of Vthe wheel-othet is, an are through which the wheel revolves intwenty-four hours-with the exception of the full pert F whieh is largerthan the rest. This part F with an adjet-cent recess, 1), covers an arcof two-sevenths of the eircumference. B. isthe bolt of the time-lock,ttrranged in the support K, and is capable of a, longitudinal motion. Itis kept thrown out by the spire-l spring S in the cylindrical chamber inthe support K, through which chainber the bolt B passes. (See Fig. 2.)The springS bears against the. ring or shoulder on the bolt 13, and egains t the cup 7a, which closes the chem benund which is k p in r e e'byme l r s! "Through the cap it is a, passage for the tongue t of the boltB. The support K is dovetailed, and secured by the'.s'crew a into theblock N, which is firmly fastened to the wail C of the lock-case. (riceFig. '1.) By unscrewing the small screw uthesupport K end the bolt Biney be removed from the rest of the lock byslipping it out of the blockN. The bolt 13 is kept always thrown out by the [spring f5, unlesspressed back by some greater force. When one of the recesses 11 of thewheel W is opposite the bolt B, the latter is free to be pressed backinto the unlocked position; but when one of the full parts is oppositethe bolt, it can only be pressed back a short distance, viz., until thetongue t-rests against the full part of the wheel W. When one of therecesses 'b-of the wheel is back of the bolt the lock may be said to beunlocked-that is, the bolt can be pressed back but when one of the fullparts is back of the bolt it may be said to be locked. The recesses 12may be formed to correspond to as many hours as may be desired by thepurchaser. Ordinarily ten hours would be sufficiently long, in whichcase the full parts F would correspond to fourteen hours, and the largefull part F to thirty-eight hours. By loosening the milled nuts 0?. nthe wheel. W may be set in any position relative to the bolt B desired,and the nuts may then be tightened again. By setting the wheel properlythe bolt B will be'free to be pressed back or unlocked ten hours eachweek-day, (supposing each recess to correspond to ten hours,) and duringthe remainder of the time the lock will remain locked, and

on account of the large full part F which will cover the time fromSaturday afternoon.

to Monday morning, the lock will remain locked over Sunday. If the wheelW is set to open at eight oclock in the morning, or at any other hour,it will open or unlock every morning at that hour, (Sundays excepted,)and will close ten hours later.

The wheel W having been once set, the same order of things will followweek after week without other attention than the winding of thetime-movement.

As before remarked, the bolt B has a certain amount of play in and out,when the lock is Iocked--thatis, when one of the full parts of the wheelWis back of the boltand by means of this play I am enabled to accomplishthe unlocking of, the lock in case of the stoppage of the time-movementswhen the lock is in a locked condition.

The tongue tof the bolt B has onits under side at the inner extremity aprojection, f, which moves in the angular groove 9 in the face of thelever L, which is pivoted at v to the projection D on the inner side ofthe wall C. .By means of this arrangement, as the bolts move in and outto the extent of its play when the lock is locked, the lever L has anoscillating motion imparted to it, which is in turn imparted to the twosliding bars a a,

Figs. 1 and 2, pivoted to the lever L, one on each side of the pivot e.

.The projection D, extending from the wall of the lock-case, supportsthe lever L, the two bars a a, and the bearing 11 of the shaft 0, onwhich shaft are rigidly secured the two rate-h et-wheels r r, Fig. 1.The bars a a, by acting alternately on the two 'ratchet-wheels 'r 7,cause the shaft 0 to revolve, which in turn, by means of the worm orscrew upon it, re-

volves the cogged wheel m, Figs. 1 and 2, I

which carries with it the disk 2, Figs. 1 and 2, by means of the pin Eon the former, and the slot in the latter. Next above the disk 2 is thelarge wheel W. The wheel W, disk 2, and cogged wheel m, have theircenters in the same vertical line.

The hollow arbor 2, Fig. 2, on which are placed'the wheel m and disk 2,is rigidly secured to the plate 0, which is secured to the plate a ofthe frame of the time-movements, as before described. The arbor z ishollow, the-shaft d passing through it.

On the arbor 2, immediately above the plate 0', is the wheel m, free tobe revolvedon the arbor 2 by the worm on the shaft 0.

Next above the wheel m is the washer w.

Above this washer the arbor z is threaded, and screwed upon it is thedisk 2, which is also threaded.

The disk 2 is provided with a notch in its periphery, which notchengages with the pin E attached to the cog-wheel m, so that as the wheelm is revolved by the shaft 0 the disk will also be revolved.Consequently it will be seen that the disk 2 is revolved by themoveinent back and'forth of the bolt B, and as the disk is screwed ontothe shaft 2 it gradually rises until finally the lug b on the upper sideof the disk 2 engages a similar lug, b, on the under side of the wheelW, causingthe latter to revolve also. Thus in case of any stoppage ofthe wheel W, which would leave the lock in a locked conditionthat is,with one of the'full parts F or F back of the bolt BI can in a longer orshorter time by alternately pressing in the bolt B, and allowing it tospring back, cause the wheel W to revolve until one of the recesses b isbrought back of the bolt, when the bolt may be fully retracted.

The time that will be required for the above operation will depend uponthe dis tance the disk 2 has to rise before engaging with the largewheel W. By unscrewing the pin E on the wheel m the disk 2 is free to berevolved independently of the wheel m, and

so can be set at any distance below the wheel W desired, by screwing itup or down on its arbor z, and the pin Ecau be replaced. Thus the timerequired for unlocking may be made to be anything from a few minutes upto the longest limit, say ten to twelve hours.

The milled nuts 11 n are not. screwed down sufficiently tight to bindthe wheel W firmly to the shaft d, but only to insure enough fric tionto cause the wheel W to rcvolvewhen' the shaft d is revolved by the timemechananism, but not so much friction but that the wheel W may berevolved on the shaft cl by the unlocking mechanism without strainingthe time-movements.

It is to be observed that the-only function of the wheel W is to presentalternately a full part F or F and a recess, 12, to the bolt B, and thatit is only in case of the attempted forcing back of the bolt, when afull part is days.

back of it, that the wheel W exerts any control over anything externalto itself. If desired, the wheel W may be made without any full part F,as shown in Fig. 6. When the wheel is thus constructed, a recess, 12, isprovided for each day of the week, Sundays included, and a full part foreach night. Ac-.

companying the wheel W are several segments F Fig. 8, by means of whichone or more of the recesses 12 may be closed, and the lock thus made toremain looked over one or more days, as may be desired. Occasionally itmight be desirable to have the lock capable of remaining locked for alonger period than six days, (which would be the longest limit for alock having a wheel with seven recesses b, as the seventh recess wouldhave to be left open or the lock would not unlock at all) as nine days,for example, :in which case the wheel W would be provided with tenrecesses and ten full parts F, and the necessary nnm' ber of segments Fand the time movements would be so geared as to revolve the wheel W oncein ten days, instead of once in seven It now remains to be shown how Ilocate this look 011 the door of a safe or vault, and arrange so that byturning the spindle ot' the train-bolts or of the combination-lock backand forth a reciprocating motion may be imparted to the bolt B, and thusthe unlocking of the timelock be effected from the outside of the safeor vault independently of the time movements.

In. Fig. 4 J is the jamb of the door; D, the door; R, the train-bolts;S, the spindle, by which the train-bolts are thrown. P is thecombination-lock ;\T, the time-lock; B, the bolt of the latter. L is alever for connecting the bolts of the time and combination locks, and ispivoted to the door at c. Fig. 7 is asection through the line M M, Fig.5, limited to a portion of the bolt B of the timelock, the lever L, anda part of the trainbolts R. The time-lock T is so placed on the doorthat when the train-bolts B are thrown out or locked, the bolt B of thetime-lock (it being thrown out by the spring S) just bears against it,so that the least motion backward ot' the train-bolts will impart a likemotion to the bolt B. The train-bolts R arethrown by means of thespindle S, which passes through the door and is operated by a handleattached to its outer end. By turning the spindle in one direction, asto the right, the bolts R are thrown out, and in the contrary directionthey are thrown back. But when the train-bolts are thrown back theypress back the bolt B of the time-lock, and when they are thrown out thebolt of the time-lock is also thrown out by the spring S, and thisreciprocatingof the bolt B, if continued, will unlock the timelock (itlooked) as previously explained. Thus 'We see that, by turning thespindle of the dependently of the timemovements. By connecting the boltB of the time-lock with the train-bolts R, as indicated by the dottedline, Fig. 4, the spring S may be dispensed with, as, in that case, bothmotions, in and out, would be imparted to the bolt B by the trainbolts.While the combination-lock P is locked the train-bolts R cannot be movedat all, and, consequently, the unlocking mechanism of the time-lockcannot'be operated. When the combination-lock is unlocked thetrain-bolts may be thrown clear back, and thedoor opened, provided thetime-lock T is also unlocked. When the latter is locked, however, thetrainbolts can have only a slight motion backward, not enough to permitof opening the door,

but sufficient to work the unlocking apparatus of the time-lock.

The arrangement of the bolt-work on safe andvault doors varies greatly,and, of course, each time-lock would have to be placed on its door in amanner to conform to the particular bolt-work. Occasionally thebolting-mechanism is placed upon the jamb of a safe, with theoperating-spindle passing through the jamb, in which case it might benecessary to place the time-lock on the jamb also. The lever L and thebolt 10 of the combination-lock form the connection between the bolt Bof the timelock T and the operating-spindle of the combination-lock P,by means of which and the turning of the spindle of the latter back andforth the unlocking of the time-lock will be effected independently ofthe time-movements. The bolt 10 of the combination-lock is thrown in andout by turning the spindle of' the combination-lock back and forth. Thelever L is pivoted to the door D at c, and is free to swing or move onthe pivot in a plane parallel to that of the door. The lever L extendsfrom the pivot 0 under the bolt B of the timelock to the bolt 10 of thecombination-lock P,

to the under side of which bolt itis pivoted or attached. A portion ofthe under side of the bolt B of the time-lock is cut away, thus forminga shoulder, as shown in Fig. 7. The lever L passes underneath thiscut-away portion of the bolt B, and has a tongue or projection, t,

Fig. 7, extending from it sufficiently to engage the shoulder on thebolt B. Now, when the boltp of the lock P is thrown back by turning thecombination-lock spindle to the right or to the left, as the case maybe, the lever L is moved with it, and the tongue t, engaging theshoulder on the under side'of the time lock bolt B, presses the latterback. On throwing the bolt of the lock P out again by a reverse motionof the spindle all the motions above stated are reversed, and the bolt Bof the time-lock is free to spring out again; thus by a repetition ofthese .two motions of the lock-spindle, to the right and then to-theleft, or vice versa, a reciprocating motion is given to the bolt B ofthe time-lock, which, if continued, will finally unlock it, if looked,as before shown.

It will thus be seen that I am enabled to unlock-the time-lockindependently of its timemovements turning the operating-spindle of thetrain-bolts alternately to the right and to the left, and that I am alsoenabled to dothe same by turning the spindle-of the com:

bination-lock alternately to the right and to the left.

A similar connection might be made lie-- tween the time-lock and anyother spindle passing through thedoor or'jamb of the door. It-may not beadvisable to have the time lock under the influence of more thanonestrong box where it may be an object to'have such aelock placed.

I claim as my invention-- 1-. The wheel W, arranged to be operated bythe time-movements, and having onits' cirj cumfi'are'nc'e'alternaterecesses and full parts,
